As shown in FIG. 4, which is a configuration block chart of the present invention, external city power is input from the block 2.1 power measurement module and then proceeds to block 2.2 AC / DC power supply. Thus, all power consumption data can be measured, and the block 2.6 microprocessor reads and records.

Block 2.2 Most of the DC power output from the AC / DC power supply is provided to Block 2.3 dimming control and status reading interface. As a result, the eight external LED lamps are turned on. Separately, some power is provided to the block 2.7 power diversion protection and control circuit to power the inventive system.

The block 2.6 microprocessor can detect the status of the external wall switch and the information of the block 2.5 control mode set interface based on the block 2.4 scene mode input interface.

Hereinafter, the operation principle and operation of each block of the controller of the present invention will be described. 5 to 10 are block circuit diagrams of the present invention, and FIG. 11 is a circuit diagram of a mechanical switch and electronic touch switch for group control and dimming control to which the present invention is attached.

FIG. 5 is a circuit diagram (block 2.1 circuit diagram) of the power measurement module of the present invention. In the figure, U1 is a switch type power supply stabilization IC, and the local power supply P1 enters the D pole (PIN 5) of U1 via R5 and D2. On C4, it is a DC power supply that reaches several hundred volts, and the 5VA power supply required by this module is stably output through the action of U1 and surrounding D1, D3, R1, R4 and C1, C2, C5, L1. To do. The value is determined by the electric resistance ratio of R1 and R4, and D4 and R8 are 5VA power supply indicators. The 5VA power supply is provided and used only for this power module.

In FIG. 5, U6 is a power measuring IC, which inputs a local power voltage of an appropriate ratio and consumes current. From U6, voltage (V), current (A), watt (W), watt hour ( Numerical data such as Wh) and power factor (PF) can be obtained. In the figure, the voltage input of U6 starts from P1 and undergoes voltage division of R23, R24, R25, and R27. That is, the voltage of R27 is directly proportional to the P1 input voltage.

There are two types of U6 current measurement signals. Under high current (more than 15A), P2 and P3 pass through the transformer CT1 through one conductor. That secondary current produces a corresponding voltage on R15. The voltage is directly proportional to the current consumption (at this time, R16 and R17 are not installed), and the measured current signal is guided to the V1P and V1N pins of the power measurement IC U6 via R20 and R21. In this embodiment, since the total power consumption is 300 W or less, CT1 and R15 are not used for current measurement, R16 and R17 having low resistance values are used, and the voltages at both ends of R16 and R17 are directly read. The voltage is also directly proportional to the current consumption.

The electric resistance and capacitor at the U6 input signal processing end in FIG. 5 include C13, C14, C15, C16, C17, C18, and R26 for the purpose of test signal noise filtering. U6 power measurement IC uses PIN-9 voltage as a reference for measurement. C19 and C20 are used to stabilize the reference voltage. X1 is a precision oscillator, and when used for measurement time base calculation, becomes the basic time base of energy (Wh) conversion. The measurement results are connected to the U4 MCU from the SI, SO, and SCK signal lines. That is, the MCU (U4) of the module reads the power measurement data of U6 using a serial SPI interface.

In the figure, Q1 is controlled by the microprocessor U4.
Perform OFF and POWER ON RESET again. The microprocessor U4 of this module stores adjustment data in the U5 memory, and when used, reads the adjusted correction data through the CS1, SO, SI, and SCK signal lines, and passes through the ADE-CS, SO, SI, and SCK signal lines. Can be loaded into the measurement correction register of the U6 power measurement IC. At the same time, the measured value of U6 is read through the homologous signal line, loaded into the memory IC of U5, and the measured value is passed through the TXD-OUT and RXD-IN signal lines through the photoisolator ICs U2 and U3. Can transmit on RXD and TXD pins. Accordingly, the master CPU of the present invention can read the immediate or historical measurement data of the power measurement module through TXD and RXD.

FIG. 6 is a circuit diagram of the dimming control and status reading interface of the present invention (circuit diagram of block 2.3). There are 8 sets of LED Control-1, each of which controls 8 LED lamps, and the system and circuit structure are similar. Hereinafter, LED control-1 will be described as an example. As shown, the power supply provides 48V DC power and goes through the F1 fuse to Q2. L1-OUT1 and L1-OUT2 in the figure are connected to an external LED lamp, R45 is the current electrical resistance measured by it, and the higher the voltage on R45, the larger the current flowing through the external LED lamp, Directly proportional.

In the figure, U7A is a comparator. As shown in the figure, if the negative input (PIN-6) of U7A is larger than the positive input (PIN-7), the current LED current is smaller than the set brightness current. Is shown. At this time, U7A outputs LOW, the Q4 collector pole becomes HI, and Q2 becomes conductive. This increases the voltage provided to the LED lamp and increases the brightness. If the current increases, the voltage on R45 will also increase until the positive input (PIN-7) of U7A is greater than the negative input (PIN-6). At this time, U7A outputs the HI potential, turns on Q4, and turns off Q2.

That is, the power supply voltage provided to the external LED lamp and the flowing current can be automatically controlled simply by changing the HI or LOW signal of L1-1, L1-2, L1-3, and L1-4. In this way, the brightness is controlled, and this circuit is an electric circuit in which L1-1, L1-2, L1-3, and L1-4 have a fixed ratio of R43, R47, R49, and R53 by four logic input voltages. Through the resistance value and the R51 voltage division, 16 types of voltages (24 = 16) can be obtained, and 16 types of dimming current and 16 types of dimming luminance can be obtained. In other words, the present invention can convert four digital voltage levels to 16 linear voltages and set 16 dimming currents.

In FIG. 6, 60V-IN (60V) provides a voltage higher than the power supply 48V, and becomes the drive voltage of Q2 through the guides of C27 and R31. R29 and ZD2 limit and protect the drive voltage of Q2. D6, L3 and C23, C24 constitute the energy storage circuit of the switch type power supply. R37 and R41 constitute a Schmitt circuit. Thereby, the U7A comparator can control ON or OFF of Q2 more stably. Through automatic comparison control of the voltage of R45 (the current that actually turns on the LED) and the voltage of R51 (the circulating current set for the LED), the ON / OFF ratio of Q2 is automatically adjusted. Through the smoothing filters of L3, C23, and C24, the current that the current LED output voltage circulates can just satisfy the set brightness, and a switch type power supply with high efficiency and low wear can be achieved. However, because it is very close to a constant DC current (not a general pulse PWM method), the brightness of the LED lamp is uniform and does not blink, no noise is generated, and the LED can be instantaneously overloaded to drive the LED. As a result, the life of the LED lamp can be extended.

In FIG. 6, the U16 serial conversion parallel IC outputs eight types of signals TP1 to TP8, and controls ON and OFF of eight photoisolator ICs U13 to U22 one by one. Taking the first set as an example, as shown in the figure, TP1 controls the ON or OFF of the U13 photoisolator IC, and in accordance with D22, the current LED- It is directly proportional to the output voltage of 1. The circuit principle and operation of the other LED controls 2 to 8 are similar to those of the LED control-1 circuit and will not be described again.

In other words, the controls TP1 to TP8 can start each pair of photoisolator ICs one by one, pass through R134, R135 partial pressure and AD1 conversion, and measure the current drive voltage of each group of LED lamps in turn. Can know the power consumption and status of each LED lamp. Since the LED lamp is composed of a large number of single LED chips connected in series and connected in parallel, each single LED chip and connected in series and connected in parallel through the current limit control and output voltage measurement of the circuit of the present invention. However, it is possible to know whether or not it is operating normally, and thus it is possible to collect information such as main fault repair or actual lighting time.

Separately, U9, U11, U12, and U16 are series in / parallel out ICs that can control 32 digital output points, and can control the brightness of one set of four LEDs, and eight sets of LEDs. The lamp brightness can be controlled individually. In other words, U19 can control and alternately read the output voltage that is currently illuminating any pair of LEDs, and combine the currents to control the power consumption and usage status of each pair of LED lamps. Can be calculated.

U10 in the figure is a parallel-in-series-out IC, and can read four states of two wall switches and four DIP switches (SW1). This switch can set a connection address for communication according to the present invention, and can be used by selecting 0 to F. In other words, a single TCP / IP network card can be connected to and controlled up to 15 devices, that is, it can control 120 LED lamps (8 × 15 = 120), its power consumption data, usage status, etc. Data can be collected and statistics.

FIG. 7 is a circuit diagram of the microprocessor of the present invention and power supply protection and control (circuit diagrams of blocks 2.6 and 2.7). U23 is a control center of the present invention which is a microprocessor IC and includes an internal memory and can store an execution program. Read the power measurement information of the power measurement module of block 2.1 through the signal lines of the control pins TXD and RXD, and via the digital output of U9, U11, U12, U16 through the DATA, CLK, STR-1 signal lines, block 2.3 Controls LED lamp drive voltage and current magnitude of dimming control and status reading interface.

Furthermore, the output value can be measured and read using the STR-2 signal line and the output control of U19. Controls U10 through CLK1, LOAD1, and DATA-IN-1 signal lines to receive the current status of the block 2.4 scene mode input interface. U35 to U44 are controlled through CLK2, LOAD2, and DATA-IN-2 signal lines, and the setting value of the block 2.5 control set interface is read. This controls the block 2.3 dimming control and status reading interface. Thus, based on the mode set by the user, the existing wall switch can be operated to achieve the intelligent lighting control purpose in the field.

Separately, U23 microprocessor IC is further through SRXD, STXD, RS-485-EN signal line, U24 RS-185 conversion IC, block 2.8 TCP / IP data collection and storage interface through TCP / IP conversion RS-485 and data storage interface You can connect to a remote server and control it. Finally, the normal working relationship can be maintained through WDI signal line and block 2.7 power conversion protection and control circuit. If it is abnormal, the power is restarted without inputting a pulse to the U28 WDI (PIN-4) in FIG. In other words, when the system (program) is operating abnormally, the WDI signal disappears, or if the system voltage (5V) used is abnormal, the U28 WDT-RST (PIN-3) changes from LOW potential to HI potential. change. Thereby, Q20 becomes conductive, Q19 becomes OPEN, Q18 becomes OPEN, and the power supply (PIN-28) supplied to the microprocessor U23 is cut off. That is, 5V-OUT becomes 0V. Then restore power, complete the POWER ON RESET process, and restart the system.

In FIG. 7, the low-voltage 5V power supply used by the present invention is provided from an external AC / DC power supply 48V, and the U25 switch type power supply IC and its surroundings D30, D31, R148, R149, C66, C67, C68, L11, Through the arrangement of parts such as L12, a stable 5V power supply can be obtained with high efficiency from a voltage of 48V and provided to each block circuit of the present invention.

In FIG. 7, the 60V POWER MOS drive power supply (ie, 60V-IN) used by the present invention is boosted by 48V-IN. In the figure, U30 is a switch-type power supply IC that combines the surrounding D32, ZD20 (12V Zener diode) and the placement of components such as R158, U29, C70, C71, and the 48V voltage is boosted to a 12V power supply. Output power can be obtained with high efficiency and provided to the POWER MOS drive of each dimmer.

FIG. 8 is a circuit diagram (circuit diagrams of blocks 2.4 and 2.5) of the scene mode input interface and control mode set interface of the present invention. The present invention can use an existing wall switch and defines two states of four switches. As shown in the figure, AC-L1 and AC-N1 indicate light sources controlled by one set of existing switches. Therefore, it can be used as it is without changing the wiring of the original switch. When the original switch is ON, one AC voltage is originally provided between AC-L1 and AC-N1. In the present invention, the AC power source is divided into two circuits, positive and negative, using two diodes D40 and D41. As shown in the figure, when current flows through D40, R160, D33, U31, and U53 in the positive half cycle, R160 limits the electric resistance. D33 is an LED group indicator, and U31 and U35 are photoisolator ICs. If the existing switch is in the ON state, U31 conducts during the positive half cycle, so that R162 gets a single 5V high potential and AC-SW1 is positive.

In the negative half cycle, R158 limits the electrical resistance as current flows through D41 and R158, D34, U32. D34 is an LED dimming indicator, and U32 is a photoisolator IC. If the existing switch is in the ON state, U32 conducts during the negative half cycle, which causes R163 to get a single 5V high potential. Therefore, if one switch on the existing wall is replaced with two switches and one diode is connected to each switch, one of the switches can circulate only the positive half cycle, and AC-SW1 The potential can be controlled and group control can be performed.

The other switch allows only the negative half cycle to flow, and can control the AC-SW2 potential, providing dimming control. That is, in a situation where the wiring is not altered, one switch is replaced with two, and each has a group control and dimming control operation interface. Since the electrical resistance value of R158 is designed to be smaller than that of R160, when the wall switch is ON, the negative half-cycle current is larger than the positive half-cycle current. This is because the design corresponds to the attached electronic touch switch of the present invention (see FIG. 11). In this way, positive and negative half cycles can be measured, the synchro positive half cycle control is used, the group is controlled, and the light control is controlled by the negative half cycle. Thus, similar control objectives are achieved as in the two mechanical switches.

The situation of other AC-SW3 and AC-SW4 is also similar, corresponding to another wall switch or one electronic touch switch attached to the present invention, using different operation methods, homologous control Achieve the goal. The AC-SW1 to AC-SW4 signals are indirectly acquired by the microprocessor IC U23 via the parallel conversion serial IC U10 of block 2.3. That is, the microprocessor can detect the ON / OFF message of the wall switch at any time, and can analyze the meaning of continuous switching. The U23 microprocessor executes the program and controls the lamp on / off and brightness desired by the user.

In FIG. 8, the present invention divides four wall switches into two areas. Each area is defined using two switches. Among them, AC-SW1 defines area 1 group switch, AC-SW2 defines area 1 dimming switch, AC-SW3 defines area 2 group switch, and AC-SW4 defines area 2 group switch. Define dimming switch. Each of SW2, SW3, SW4, and SW5 in the circuit diagram 8 is 8 sets of DIP switches. Each set represents one LED lamp. Each time AC-SW1 is switched, the contents of the LED lamps to be lit are made to correspond. For example, SW2 sets 1, 2, 3, and 4 to ON, sets 5, 6, 7, and 8 to OFF, and SW2 sets 1 to ON and sets 2 to 8 to OFF. Thereby, AC-SW1 lights LED lamps 1 to 4 when switched for the first time, and lights LED lamp 1 when switched for the second time. The same applies to the third and fourth times. That is, SW1 to SW4 can set LED lamps to be lit at each stage of AC-SW1 (4 stages in total).

SW5 is 8 sets of DIP switches, and 1st to 7th sets each represent a percentage of dimming. Define AC-SW2. The brightness of each switching stage is a maximum of seven stages. In the present invention, the first stage is 100%, the second stage is 80%, the third stage is 60%, the fourth stage is 50%, the fifth stage is 40%, the sixth stage is 10%, and the seventh stage is 5%. For example, in SW5, 1, 4, and 6 are ON, and others are OFF. Each time AC-SW2 is switched OFF-ON, the LED lamp changes from 100% (full light) to 50% (half light), and further 10% (low light). In other words, the present invention can enhance the group switching and dimming function of the existing wall switch through the switch setting, and can easily meet the needs according to the needs of the field, Can achieve the goal of saving and convenience.

Each switch in FIG. 8 corresponds to one parallel in series out IC. For example, SW1 corresponds to U1, SW2 corresponds to U2, and so on. Through the signal combination of the microprocessors CLK-2, LOAD-2 and DATA-IN-2, the messages of the SW-1 to SW-10 switches can be read into the U11 microprocessor one by one. By adapting the current status of AC-SW1 to AC-SW4 wall switches and the operation of the U11 program, the lamp can be reliably controlled for the first time, and the current lighting needs can be achieved. Separately, the 8th set DIP switch of SW5 and SW10 is defined for the purpose of self-measurement of group setting and dimming setting, quickly reveal the relationship between each lamp and group, and automatically dimming data of each lamp Established on the basic reference information of dimming control and main maintenance.

For example, when SW10 is set to ON, the microprocessor program activates and establishes dimming data for each LED lamp. First, start with the first LED lamp and start dimming from the first stage (as described above, the L9 to L4 output levels of U9 can be dimmed in 16 stages, including one OFF). Further, the drive voltage of the current LED lamp is read (as described above, corresponding to the TP1 to TP8 control, the current drive voltage of each LED lamp is measured in order from AD1). Next, recording is performed corresponding to each stage until the 16th stage of dimming is completed, and this is repeated for the second LED lamp until all of the eight LEDs are completed.

In other words, the function in this section can automatically establish the drive voltage at the time of dimming each LED lamp, and there are a total of 128 data (16 × 8). Through the program calculation, you can know the maximum current of each lamp under the rated voltage drive of 48V. That is 100% brightness. This distinguishes and automatically calculates the number of currents to be set at each stage of dimming for each lamp, and thus LED lamps with different standards are made intelligent and automated, and stable dimming using a constant current usage method according to the ratio. It can be performed.

Separately, the drive voltage corresponding to each stage current of each LED lamp is simultaneously established. In actual use, the drive voltage of the current LED lamp is measured at any time in order, and after a comparison and calculation of the program, when a certain ratio error is exceeded, the chip or circuit in the LED lamp has failed. Indicates that When SW5 is set to ON, the microprocessor program starts a self-test process. Start with the first LED lamp. According to the set dimming step, the full light is automatically converted step by step and stopped at the darkest stage set by the lamp. Subsequently, the second lamp is turned on, and the last one is turned on one by one. This is repeated until SW5 is set to OFF. The purpose is to enable an engineer or user to quickly check the group correspondence and dimming status of each lamp.

In FIG. 8, one emergency switch is specially designed. As shown in the figure, SW14 is normally switched to the general state, but the 48V-POWER power supplied from the outside is supplied to 48V-IN via the NC contact of RY2, and 48V-IN is further connected. After that, 12V, 5V and 60V (see FIG. 7) and LED drive power (see FIG. 6) are provided. If a problem or failure is encountered, switch the SW14 switch to a transient state. At this time, RY2 operates and the 48V-POWER power supply supplies 48V via the NO contact of RY2. In other words, leave only a few circuits around the emergency switch in this section, turn off all the power supplies mentioned above, and use the 48V power supply directly.

At this time, if the first set of wall switches are in the ON state, U53 and Q20 are made conductive and RY1 is changed to the ON state. As a result, 48V is supplied directly to the positive ends of L1-OUT-1 to L8-OUT-1 via D62 to D69 and output. In this way, eight LED lamps are lit directly. If the wall switch is OFF, RY1 is also OFF and all 8 LED lamps are turned off. That is, when a failure occurs in the device of the present invention, a very few parts are energized, and this lighting system maintains the simplest LED lamp all-off and full light switch function. This prevents inconvenience from becoming too large.

In this figure, the Zigbee (registered trademark) module J34 used uses a 3.3V power supply. Therefore, it is necessary to provide a stable working power supply of 3.3V with a voltage stabilizing IC from U49 5V to 3.3V. The J34 Zigbee (registered trademark) communication module communicates with ZTXD and ZRXD by the microprocessor U23 of FIG.

FIG. 11 is a circuit diagram of a mechanical switch and electronic touch switch for group control and dimming control to which the present invention is attached. This accessory device can be replaced with a single switch on the existing wall surface. In a situation where the wiring is not altered, the two switches or two touch buttons provided by the accessory have group control and dimming control functions, respectively.

The principle will be described below.
In the figure, SW15 is one switch on the original wall, and it is replaced with two switches such as SW16 and SW17. Furthermore, it is connected in series to two diodes D74 and D75, respectively. As a result, the switch SW16 can control only whether or not a positive half-cycle current is supplied, and does not affect the negative half-cycle. Therefore, the potential of AC-SW1 in FIG. 8 can be controlled. In this way, the group switching function is controlled, and the switch S17 can only control whether or not to supply a negative half-cycle current, and does not affect the positive half-cycle. Therefore, the potential of AC-SW2 in FIG. 8 can be controlled. Thus, the dimming function is controlled. That is, the present circuit and the present invention can replace the original one lamp ON-OFF switch with two switches and control the group switching and dimming functions, respectively.

In addition, the control of the switch installed on the wall surface of the present invention can be replaced with an all-electronic touch switch. In this way as well, one switch can be replaced with two touch switches to control group switching and dimming functions, respectively. In the figure, BD1 is a bridge-type rectifier, and therefore, whether it is positive or negative half cycle, it is output from the positive end of BD1, and the current is charged by C115 via Q23, R224, and D72. Since D73 is 12VZENER, C115 is stable at 12V. Furthermore, a stable 5V power supply is provided via the U55 voltage stabilization IC. According to the present invention (the resistance values of the current limit registers R158 and R160 of the positive and negative half cycles in FIG. 8 are different. Since the electrical resistance value of R158 is smaller than R160, the negative half cycle current is larger than the positive half cycle. Large) intentionally mismatch the positive and negative half-cycle currents.

That is, the negative half cycle current flowing through U54 is greater than the positive half cycle. That is, on the electric resistance of R227, potentials having different widths (cycles) can be obtained, and the width of the negative half cycle is wider. The U58 is a microprocessor that can determine the R227 HI potential time and distinguish between positive and negative half-cycle cycles. U55 is a touch IC. When the hand approaches KEY1 (group), U58 controls ON or OFF of positive and negative half cycles based on the time base signal of R227. The method controls Q22 through R228, and in the positive half cycle, if Q22 is ON, Q23 is turned OFF, that is, the positive half cycle is turned OFF. If Q22 is OFF during the positive half cycle, turn Q23 ON. This turns on the positive half cycle, thus controlling the AC-SW1 potential.

When the hand approaches KEY2 (dimming), U58 controls the ON or OFF of the negative half cycle through Q22 and Q23 methods. Thus, the AC-SW2 potential is controlled. The result is the same as when using mechanical control, and the group control and dimming purposes can be achieved.

The output is connected to two sets of output terminals of LED output control LED-1 and LED-2 of the present invention, respectively. In other words, the brightness of the warm color LED can be dimmed by controlling the output of LED-1, and the brightness of the cool color LED can be dimmed by controlling the output of LED-2. Therefore, by manipulating the dimming of LED-1 and LED-2, the brightness and color temperature of the dual color LED lamp can be controlled, and the same lamp can be provided with functions of brightness adjustment and color temperature adjustment at the same time.
